WARNING: This radio is designed to generate a digital maritime distress
and safety call to facilitate search and rescue. To be effective as a safety
device, this equipment must be used only within communication range of a
shore-based VHF marine channel 70 distress and safety watch system.
7.9.2 SENDING A DISTRESS CALL
The distress call automatically includes the vessel’s DSC MMSI and Lat/Lon
position. The vessel’s position will only be transmitted if the transceiver is
properly connected to an operating GPS receiver with NMEA output.
1. Lift the red DISTRESS rubber cover on the right side of the transceiver
and press the [DISTRESS] key. “DSC DISTRESS” will appear on the top
of the LCD.
2. Press and hold in the [DISTRESS] key for 3 seconds. The LCD will count
down (3s, 2s, 1s), and afterwards the HX471S will transmit the DSC Dis-
tress Call on channel 70.
3. When the distress signal is being sent, “TX” icon will appear on the LCD.
After the message has been sent, the Distress Alarm will sound.
4. The transceiver “shadow-watches” for a transmission between CH16 and
CH70 until an acknowledgment signal is received.
5. If no acknowledgment is received, the distress call is repeated in three
minute intervals until an acknowledgment is received.
6. To cancel the distress call alarm, press the [16/9] key.
7. To send the CANCEL call:
Press the [DISTRESS] key, then press the [] or [] key until “CAN-
CEL” is shown on the LCD. Press the [DISTRESS] key.
NOTE: When a GPS receiver with NMEA output is connected via the CD-25
Charger Cradle, the vessel’s position is automatically transmitted with the
distress call. The HX471S will remember the position input from the GPS
until the radio is turned off.
7.10 SIMPLEX/DUPLEX CHANNEL USE
All Marine channels are factory-programmed in accordance with FCC (USA),
Industry Canada and International regulations. The mode of operation can-
not be altered from simplex to duplex or vice-versa. Simplex (ship to ship) or
duplex (marine operator) mode is automatically activated, depending on the
channel and whether the USA, International or Canadian operating band is
selected.
